DAAAAANG! + ANGST = Dangst.
A deep seated feeling of dread that develops when a strong, instant, physical attraction goes terribly wrong for someone with social anxiety. The sufferer is so paralyzed by a profound and deep-seated spiritual condition of insecurity and despair that they are unable to make even the most rudimentary of social gestures toward the object of their affection, and are fully aware that they are wasting a golden opportunity and failing themselves. Rather than just nut up and initiate conversation they will spend their time(possibly much longer) in the presence of the person in extreme inner turmoil- alternately admonishing themselves for not making a move and imagining pleasing possible social/sexual scenarios with said hot person.

noun:
Much dangst will be suffered at this Valentine's Day rpg tournament tonight.
